Maintenance

Warning! Read 'Safety information' on page 6 before servicing the fixture.
Refer any service operation not described in this user manual to a qualified
service technician.
Excessive dust, smoke fluid, and particle buildup degrades performance,
causes overheating and will damage the fixture. Damage caused by inadequate
cleaning or maintenance is not covered by the product warranty.
Disconnect mains power before cleaning or servicing the fixture.
Service fixtures in an area where there is no risk of injury from failing parts, tools
or other materials.

Cleaning

The cleaning of external optical lenses must be carried out periodically to optimize light output.
Cleaning schedules for lighting fixtures vary greatly depending on the operating environment. It is
therefore impossible to specify precise cleaning intervals for the fixture. Environmental factors that
may result in a need for frequent cleaning include:
•
Use of smoke or fog machines.
•
High airflow rates (near air conditioning vents, for example).
•
Presence of cigarette smoke.
•
Airborne dust (from stage effects, building structures and fittings or the natural environment at
outdoor events, for example).
If one or more of these factors is present, inspect fixtures within their first 100 hours of operation to
see whether cleaning is necessary. Check again at frequent intervals. This procedure will allow
you to assess cleaning requirements in your particular situation. If in doubt, consult your Martin
dealer about a suitable maintenance schedule.
Use gentle pressure only when cleaning, and work in a clean, well-lit area. Do not use any product
that contains solvents or abrasives, as these can cause surface damage.
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 10 minutes.
2. Vacuum or gently blow away dust and loose particles from the outside of the fixture and the air
vents at the back and sides of the head and in the base with low-pressure compressed air.
3. Clean the lens by wiping gently with a soft, clean lint-free cloth moistened with a weak
detergent solution. Do not rub the surface hard: lift particles off with a soft repeated press. Dry
with a soft, clean, lint-free cloth or low-pressure compressed air. Remove stuck particles with
an unscented tissue or cotton swab moistened with glass cleaner or distilled water. You can
remove the lens tube to clean the rear side of the lens if needed.
4. Check that the fixture is dry before reapplying power.

Fuse replacement

If you need to replace a fuse:
1. Disconnect the fixture from power and allow it to cool for at least 10 minutes.
2. Unscrew the cap of the fuseholder (see Fixture overview on page 9) and remove the fuse.
Replace with a fuse of the same size and rating only.
3. Reinstall the fuseholder cap before reapplying power.
4. Service and repairs
There are no user serviceable parts inside the fixture. Do not open the housing.
